Fig. 1. Time-course of the 2,4-DCP removal by horseradish in the presence of polyethylene glycol (PEG; molecular weight = 2000) or Tween 20. Reaction mixture volume = 5 mL; horseradish amount = 0.02 g; 2,4-dichlorophenol (2,4-DCP) concentration = 9 mM; H₂O₂ concentration = 9 mM; PEG and Tween 20 concentrations = 0.1 g/L; pH = 7.0; incubation temperature = 25°C.
